MECHANISM FOR PLANING- SHOES AND WEDGES.

T 0 all whom it may concern:

Be it known that I, MATTHEW MORTON, a citizen of the United States, residing at Muskegon Heights, county of Muskegon, State of Michigan, have invented a certain new and useful Improvement in Mechanism for Planing Shoes and Wedges, of which the following is a specification, reference being bad to the accompanying drawings, which form a part of this specification.

My invention has for its object novel mechanism for planing shoes and wedges, the same being more particularly designed for securely holding what are termed shoes and wedges used in the lining of locomotive axle boxes, the wedge being adjustable for taking up the wear. In order to machine these shoes and wedges correctly, it is necessary to have an apparatus which will suitaxle boxes, the wedge being adjustable for up and down from a given point at one end, the adjustability being from a parallel plane to one inch taper to the foot, for example.

My invention consists of the construction, combination and arrangement of devices hereinafter described and claimed and illus-' trated in the accompanying drawings, in which,

Figure 1 is a view in side elevation. Fig. 2 is a view showing features of the holder in plan. Fig. 3 is an end elevation of the holder. Fig. 4 is a view in cross section on the line 4- 1, Fig. 1. Fig. 5 is a view in section on the line 5-5, Fig. 1. Fig. 6 is a view of a wedge to be planed.

To accomplish the object of my invention I provide a base plate a, the same being applicable to the bed or table of any suitable planing machine indicated at b, the same being shown in Fig. 1 herewith provided with a cutter bar 0 and cutting tool (Z. The base plate is provided with a bearing 6 supported within a box receptacle f projecting upwardly at the rear end of the base plate, the bearing being supported upon said box receptacle upon pivot pins indicated at g and 7b. The base plate is also provided with lugs indicated at i and j projecting upward at thefront thereof, said lugs being machined centrally with the box receptacle. A holder or bar 70 is provided with a journal indicated at Z upon the rear end thereof, the bearing 6 being formed in the nature of a split y ring which is adjustably pivoted on the pins 9, h, the journal of the holder or bar 70 being mounted in said bearing. This bearing is so Specification of Letters Patent.

constructed as to have a perfect fit in the box receptacle so as to remove all side or lateral strain, and is so arranged that by means of a tension applied with a screw m it may be rigidly gripped in position, or by loosening said screw the holder or bar 70 may be turned or rotated as required, the holder or bar fitting between the upwardly projecting lugs 2', 7'. To this end the forward portion of said holder is preferably rounded on its lateral face as indicated at a and 7).

set screw 9 is provided to raise and lower the front end of the holder the bearing 6 turning upon the pivot pins 9, the holder being thus oscillatory upon said pivot pins. Bolts or studs 7", 1" are provided to securely fasten the holder in any position to which it may be oscillated. It will readily be seen that by this mechanism the holder or bar may be revolved upon its axis a portion of a circle, and that its front end may be easily raised or lowered, so as to adjust the holder from the pivotal points 9, 72,, so as to represent any desired taper or angle, and whereby the wedge to be planed may be made to fit the part to which it is to be applied.

The holder or bar is is provided on its upper face with a slot indicated at sin which is located a parallel steel bar t fitted in said slot so that it may be moved longitudinally of the holder. The holder is also provided with an adjusting screw it whereby. the steel bar may be moved longitudinally of the holder. The holder is also shown cut away transversely as indicated at c and w, four jaws indicated by the numerals 7 8, 9 and 10 being provided to operate in the slots 0), to, said jaws operating at right angles to the bar If. The bar 25 is constructed with wedge shaped points indicated at 11 and 12 and said jaws being similarly formed at their inner ends to match the angle of the adjacent points 11 and 12 on the sliding bar, it will readily be seen that by drawing the sliding bar forward by means of the screw it that the four jaws will be forced outward thereby centering the work located thereon to be planed, and at the same time the work will be held firmly in place. A wedge to be planed is indicated at 13. A plate or cover 14; protects the sliding bar and sliding jaws and holds them in position.

Attached to the base plate are multiple arms 15 provided with sliding blocks 16 and set screws indicated at 17 to bind against the work. The binding blocks 16 being thus adjustable to the different widths of shoes or wedges which it may be desired to plane.

These binding blocks are preferably constructed so that the outer end is lower thanon the nuts upon the screws 17 it will be evi dent that the work is forced down firmly on the top of the underlying holder or bar and at the same time is rigidly held laterally. It will be obvious that by locating the shoe or wedge over the sliding bar and turning the adjusting screw to, that the wedge will be bound internally at its sides, and then by fastening down the binding blocks 17 the work is rigidly held upon the top of the holder or bar. The device is also formed with-a block 18 so located that the work will strike there against, said block resting against the front side of the bearing 6 onthe rear end of the base. An additional support 19 is also provided secured to the rear end of the box receptacle f, said support having a bearing against the front side or front plate of the shaper or planer, and it can readily be seen that as the ram of the shaper takes its out on the inward stroke, that the cutting strains are transferred directly against the frame of the machine itself, thereby eliminating vibration and rendering the apparatus much more rigid. The base plate a preferably has a tongue and groove engagement upon the table of a shaper or planer so as to be self alining.

This invention is particularly adapted to an ordinary draw out shaper, but may be used on a planer or other reciprocating machines.

I do not limit myself to the pivoting of the rear end of the holder or bar 0 upon pivot pins 9, h, as for this purpose a ball or socket or other suitable joint might be used if preferred.
